648891-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 648891-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,8,8,9 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 648891-68:
(8*6)+(7*4)+(6*8)+(5*8)+(4*9)+(3*1)+(2*6)+(1*8)=223
223 % 10 = 3
So 648891-68-3 is a valid CAS Registry Number.
